Olympic Track and Field Schedule 2012: Top Events to Watch on Wednesday

If you like sprinting, you are going to love the track and field events on slate for Wednesday at the 2012 London Olympics.

We've got a stacked field of ladies in one event, two of track and field's biggest stars in another and even some hurdles in the mix for good measure.

It's all about the track at London this week, and Wednesday is as good as it gets. Here are a few events you don't want to miss.

Let's be honest—any opportunity you get to watch Usain Bolt and Yohan Blake run, you have to take. While the world's top sprinters won't be in the same heat, each will highlight the semifinal round.

Of course, there are more than just two runners in this field. Will Americans Wallace Spearmon, Isiah Young and Maurice Mitchell advance to the final? Who will potentially find medal stand alongside Bolt and Blake?

Also keep your eyes on Spearmon, France's Christophe Lemaitre and Churandy Martina of the Netherlands.

Campbell-Brown has won consecutive gold medals in the event, while Felix has taken the past two silver medals. But you can't count out Fraser-Pryce (consecutive gold medals in the 100-meter dash), Richards-Ross (who won gold in London in the 400-meter dash) or Jeter (silver in London in the 100-meter dash), either.

We don't know who will be in the final just yet—as both the semifinals and final take place this afternoon—but we do know that event favorite's Dayron Robles (Cuba) and Americans Aries Merritt, Jason Richardson and Jeff Porter are all still in contention.

Robles is the world-record holder and defending Olympic champion in the event, while Richardson won the World Championships in 2011.

The major disappointment, of course, is that China's Liu Xiang is out of the competition. The first Chinese man to ever win a gold medal in track (he won the event in 2004), Xiang fell on the first hurdle and was unceremoniously eliminated in the first round on Tuesday.

Still, this event has four runners remaining—Robles, Merritt, Richardson and France's Ladji Doucoure—who have run under 13.0 seconds. Plus, it's a sprint with hurdles.

How could it get any cooler than that?
